' 3 Claims.

- My invention relates to roongplates of the kind used in the make-up ofa roof of the general type illustrated and 'described Vin my patent1,896,685, of lViay 26, 1931. vAs previously con- '5 structed,it hasbeen found that in such roofing effective provision was not made for thecarrying off "of such water as .might condense on-the under side of the'roof plates and that there was at times a liability -for'rain water'tobe forced f l by high winds through the joints formed'between thesuccessive rows of the roofing plates and the object of my invention isto provide a rooiing plate structure which will at the same' timeprovide' for theready escape'of water of'v'condensation formed '15 onthe underside of the plates and prevent water from being blownupwardlythrough the joints formed by the lapping plates and also toadapt theroof structure asa whole to the most advantageous embodiment ofsuch improved plates and my inventionr consists in forming on the uppertop surface ofwa rooiing plate provided with upwardly extending ribs orflanges along its sides and with a hood like formation extending fromthe bottom edge of the plate centrally upward to l" a point below thetop edge of the plate, a pair of ribs, the lower ends of which approachbut do not contact with each other and are located above the top end ofthe hood and which extend obliquely upward and outwardly to points at ornear the side edges of the plate and in forming above said ribs anangular rib having a closed apex and legs extending from said apexobliquely downwardly and outwardly to points near to but I not incontact with the obliquely upwardly and 4-35 outwardly extending ribsthereby affording, when such plates are assembled in a roof structure, aready outlet for water of condensation and at the same time providingeffectively against water being blown upward along the surface of theplate and between it and overlapping plates and my invention alsoconsists in certain improved features of construction in their elementsof the roof structure as adapt them for usewith the improved plates. Iam aware that roong plates have heretofore been designed with ribsdisposed upon their upper ends intended to serve the purpose for whichmy ribs are provided and that the novelty of my construction lieschiefly in the angular disposition and combination of the ribs whereby Isecure at the same time a more ready outflow of water of condensationand a more effective provision against the blowing of water upwardthrough the y joint formed by lapping plates. My invention will bebetter understood as described in connection with the drawings whichform apart ofthis specification and in which" Figure 1 is' an isometricview of a -portion of a roc-f structure of the general type of thatdescribed in my former patent but embodying my present improvements, theroofing being broken away at certain' points to better illustrate themake-up of the structure.

Figure '7 is a'transverse section on the line 'T4-'7 of Fig.5, and* Y l-Figure 8 is af-longvitudinalsection onthe line 'F5 In the drawings, A,A, indicate roof beams. B, B, etc., my improved rooling plates providedat their upper ends with downwardly extending projections C, C, adaptedto engage the upper 30' edge of the roof beam upon which the plate islaid. D, D, are upwardly extending ribs or flanges formed on the sideedges of the roong plates and E is a hood like projection formed alongthe center of the plate and extending from its lower edge to a pointbelow its upper edge. F, F, are ribs or projections formed on the uppertop portion of the plate, the lower ends of which approach but do notcontact with each other and are located somewhat above the end of thehood, leaving between them an outflow space for water of condensation,as indicated at G. The ribs F, F, extend obliquely upwardly andoutwardly along the top surface of the plate to a point adjacent to orin actual contactwith the upwardly extending side ribs D, D, and theupper sides of the ribs thus provide for, as indicated at G1, G1, aready flow of water along the ribs to the opening G. H is an angular ribhaving a closed apex indicated at H1 and downwardly and outwardlyextending legs H2, H2, the ends of which extend comparatively close tobut not in contact with the ribs F, F, so as to leave water channels, asindicated at G2, G2, while the upper surface of the legs H2 provide forthe downward and outward flow of water, as indicated at G3, G3, and itwill be observed that while this construction provides for the freeoutflow of water of condensation, it also provides a very eifectiveobstacle to the inflow of wind or water between the surfaces of lappingplates.

As in my former patent, cap pieces J are provided spanning the side ribsof adjacent plates and are held in position through lugs J1 which, inturn, are secured to the roof beams in any convenient way, asillustrated by means of wedges K. Where, as shown, the ribs F extendinto contact with the lateral ribs D, D, the downwardly extendingportions of the cap pieces J are raised or cut away as indicated at J2so as to clear these ribs when the cap pieces are assembled with theroof plates. The lower ends of the arc shaped cap pieces are closed bytransversely extending webs, as indicated at J3, and these webs areextended downward below the edges of the cap pieces J so as to come incontact with or close to the surface of the roong plate B at a pointbetween the top of the hood E and the lower ends of the ribs F, F. Itwill be seen that the downwardly extending portion J3 of the cap piecesaffords a wind-break directly in front of the ends of the ribs F, F.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent, is:

l. In a roong plate provided with upwardly extending ribs along itssides and having an upwardly extending hood like formation extendingalong its center line from the bottom edge of the plate to a point atsome distance from the top edge of the plate, the improvement whichconsists in forming upon the upper side of the upper portion of theplate a pair of ribs the lower ends of which approach but do not contactwith each other and which extend obliquely upward and outward and informing above said ribs an angular rib with a closed apex, the legs ofwhich extend from the apex obliquely downward and outward to a pointadjacent to but not in contact with the upwardly extending oblique ribs.

2. A roong plate as called for in claim 1, in which. the upwardly andoutwardly extending ribs extend at their upper ends into contact withthe upwardly extending ribs formed along the edges of the roong plate.

3. In a roof structure comprising supporting beams, roong platessupported on said beams having upwardly extending ribs at their sideedges and centrally located hood like structures extending from theirbottom edges toward but not to their top edges, said plates being set inparallel rows in which the individual plates of each row are spacedapart from each other and in which the plates of adjacent rows are setin staggered relation to each other and cap pieces extending over theside ribs of the roong plates having locking lugs extending downwardlybetween the edges of the plates and means for securing said locking lugsto adjacent roof beams, the improvements which consist in forming uponthe upper top surface of the roong plates which are overlapped by anupper row of roofing plates a pair of upwardly extending ribs, the lowerends of which approach but do not contact with each other at a pointsomewhat above the top of the hood like formation of the plate and whichribs extend obliquely upwardly and downwardly into contact with thelateral ribs of the plate and in forming on the upper portion of theplate above said ribs an angular rib having a closed apex and downwardlyand outwardly extending legs which approach but do not contact with theupwardly and outwardly extending ribs, in forming the cap pieces withtheir uppermost downwardly extending portions cut away to give passageto the upper ends of the oblique ribs formed on the plate and with atransversely and downwardly extending web at their lower ends extendingdownward to such distance as will cause its lower edge to comesubstantially in contact with an underlying plate in the assembled roofstructure.
